Overview

The tank example is a fairly simple model of a tank, inlet valve, and outlet valve. This example is shown in the following notebooks.

Models

• tank_model.py: Base tank model.

• tank_optimization_model.py: Tank model used for optimization

Scripts and tests:

• test_tank.py: Tests various tank behaviors.

Notebooks

• Hold-up Tank Model uses the SampleApproach class to model human interactions with the modeled system (in tank_model.py).

• Tank Optimization shows how design and contingency management of a system (in tank_optimization_model.py) can be co-optimized with the ProblemArchitecture class, as well as external solvers.

The support files include various implementations of the tank model.

• The baseline Tank Model (tank_model.py), a dynamical implementation of a human-operated tank system to show how fmdtools can be used to model human errors.

• A demonstration Optimization Tank Model (tank_opt.py), resilience optimization architectures using ProblemArchitecture.

• The main Tank optimization model (tank_optimization.py) similar to tank_model and tank_opt and is a dynamical implementation of a tank system with contingency management.
